According to classified papers described by the Spanish daily El Pais as Washington’s and NATO’s written responses to Russian security requests, Washington is prepared to consider agreeing not to deploy ground-launched missiles or combat forces in Ukraine if Russia agrees to do the same.

El Pais did not specify how the documents were obtained.

The United States and its NATO allies are also ready to discuss reciprocal measures to avoid dangerous incidents in the air or at sea, and to reassure Moscow that there are no Tomahawk cruise missiles stationed in Romania and Poland, according to the documents published by the paper.
